Jacobi transformation conjecture for VOA characters

Let $V$ be a rational vertex operator algebra of CFT type, let $M$ be an irreducible $V$-module, and let ${\mathfrak h}$ and $L^{\circ}$ be the spaces defined in the source, with $L^{\circ}$ the dual lattice of the lattice $L$. For $v\in{\mathfrak h}$ and $\alpha\in L^{\circ}$, write $\chi_M(v,\tau)$ for the character associated with $M$. Jacobi transformation conjecture.

$$\chi_M(v+\alpha\tau,\tau)=e^{-2\pi i(v,\alpha)-\pi i(\alpha,\alpha)\tau}\chi_M(v,\tau).$$

This predicts the elliptic transformation law for the characters of irreducible modules and is part of the expected Jacobi-form behavior of VOA characters. The source gives no further information about its resolution.
